Launch Jupyter with Just “jn” from command line : A Quick Setup

Stop typing jupyter notebook from terminal/command prompt.

Here’s how to launch it with just  an alias jn.

Step 1: Create the Launch Script

Open a vim editor

Paste this:

#!/bin/bash
echo "Starting Jupyter Notebook from Command Line................................................"
jupyter notebook

save the file as jupyter_notebook.sh

Step 2: Create a bin Folder and Move the Script

Note : It is a good practice to create all your custom scripts under $HOME/bin directory

1. Open your terminal.
2. Run: mkdir -p $HOME/bin
3. Move your script (adjust the path if needed): mv jupyter_notebook.sh $HOME/bin/

Step 3: Add bin to PATH and Create the jn Shortcut

1. Open your shell’s configuration file (based on your environment):
   • vim ~/.zshrc (for Zsh)
   • vim ~/.bashrc (for Bash)
   • nano ~/.bash_profile (for other Bash setups)
2. Add these lines at the end:
   • export PATH="$HOME/bin:$PATH"
   • alias jn="$HOME/bin/jupyter_notebook.sh"
3. Save and close the file (in vim: wq! then Enter).

Step 4: Apply the Changes

1. Run the source command for the file you edited:
   • For Zsh: source ~/.zshrc
   • For Bash: source ~/.bashrc or source ~/.bash_profile

Step 5: Launch with jn

1. Open a new terminal.
2. Type jn and press Enter.

Enjoy your faster Jupyter launch!
